Researchers report detailed analysis of heart injury caused by yellow fever virus

Caption

Figure A shows hemorrhage and edema (arrows) close to the cardiac conduction system (asterisk), which generates and conducts the electrical signals that coordinate contraction of the heart (stained with Masson’s trichrome). Figure B shows activated macrophages expressing the antigen CD68+ (arrows) among specialized fibers of the cardiac conduction system (immunohistochemistry). The vascular alterations (hemorrhage and edema) and inflammation (cardiac infiltration by immune cells) induced by the yellow fever virus cause arrhythmias
